Minnesota Vikings will be without star running back Adrian Peterson for Wednesday's practice, but hope to have him back fit for Sunday's meeting with the Philadelphia Eagles, reports NFL.com.
The 28-year-old suffered a mid-foot sprain to his right foot in the weekend 26-29 defeat to the Baltimore Ravens in Maryland.
Head coach Leslie Frazier has been dealt a further injury blow with back-up Toby Gerhart also a doubt after straining his hamstring on a 41-yard touchdown at the M&T Bank Stadium.
Frazier said he's more optimistic about Gerhart's availability, but added that Peterson is a quick healer, and could make a surprise return to fitness, providing he makes it through the Vikings' practice on Friday.
"He can do things that most can't, in terms of coming back from injuries," Frazier was quoted saying by ESPN. "We were walking up the stairs a few minutes ago, and I said, 'Hey, what do you think?' He said, 'I'll be ready, Coach; don't worry about me.' That's Adrian."
Peterson was injured after rookie Ravens linebacker Arthur Brown tackled him while stretching for a first down in the second quarter.
An MRI scan showed no structural damage or risk of a Lisfranc injury, meaning Peterson will not need surgery, and could make a swift return to action.
